A 20.0kg object moving in the +x direction at 6.5m/s collides head-on with a 13.0kg object moving in the -x direction at 5.5m/s .
Find the final velocity of each mass if the objects stick together.
Find the final velocity of each mass if the collision is elastic.
Find the final velocity of each mass if the 20.0kg object is at rest after the collision, Is the result in part C "reasonable"? Explain.
Find the final velocity of each mass if the 13.0kg object is at rest after the collision. Is the result in part E "reasonable"? Explain.
Find the final velocity of each mass if the 20.0kg object has a velocity of 5.5m/s in the -x direction after the collision. Is the result in part G "reasonable"? Explain. Is the result in part G "reasonable"? Explain.
